Busbar Supports

Hoffman HB01231 Busbar Support for Double-T Busbar Sections. 3 pole, without end cover for both 500 mm and 720 mm Double T profiles. Quantity of 2. Use to fasten the busbars to a backpanel or modular enclosure system structure. The supports also serve as bracing against the forces present during short circuit conditions.

Hoffman HB01232 Busbar Support for Triple-T Busbar Sections. 3 pole, without end cover for 1140 mm Double T profiles. Quantity of 2. Use to fasten the busbars to a backpanel or modular enclosure system structure. The supports also serve as bracing against the forces present during short circuit conditions.

Hoffman HB01303 Busbar Holders, for Laminated Busbars. Holders fasten to 35-mm symmetrical DIN rail. A set of 4 can be used to hold 3 lengths of flexible busbars in a typical application. Quantity of 4.

Hoffman HB01508 Busbar Support. For busbars 12, 20, 30 x 5/10, 3-pole with internal screw holes. Quantity of 1. Holds the rigid copper busbars that span the enclosure width or height in place. Systems can be mounted either horizontally or vertically. These supports provide critical bracing against the forces exerted upon the busbar structure in the event of a short circuit condition. While typically mounted to the backpanel of the enclosure, these supports can also be mounted on the frame or support structure of a modular PROLINE™ enclosure system. Each support can be adjusted to accommodate all six rectangular standard sizes of rigid copper busbar.

Hoffman HB01515 Busbar Base Plate. For UL Busbar Support HB01508, HB01231, HB01232, 240 x 700. Quantity of 1. Serves as an insulator between the current-carrying parts of the busbar structure and adapter components and the metallic backpanel of the enclosure. This component is required to satisfy UL508 requirements for 2-in. over surface and 1-in. through-the-air arcing distances defined under the UL standard.

Hoffman HB01518 Busbar Base Plate. For UL Busbar Support HB01508, HB01231, HB01232, 240 x 1100. Quantity of 1. Serves as an insulator between the current-carrying parts of the busbar structure and adapter components and the metallic backpanel of the enclosure. This component is required to satisfy UL508 requirements for 2-in. over surface and 1-in. through-the-air arcing distances defined under the UL standard.

Hoffman HB01601 Earth Busbar Support. For busbars 12, 20, 30 x 5/10 1-pole for mounting individually. Includes earth and neutral labels. These single-pole supports can accommodate all six rectangular sizes of rigid copper busbar to be used for grounding purposes. When mounted immediately below the three-pole support, the 60- mm system spacing is maintained for a 4-pole system.

Hoffman HB01876 Busbar Support for Double-T Busbar Sections. 1 pole, without end cover for both 500 mm and 720 mm Double T profiles. Quantity of 1. Use to fasten the busbars to a backpanel or modular enclosure system structure. The supports also serve as bracing against the forces present during short circuit conditions.

Hoffman HB80508 Busbar Support Kit. Contains 2 busbar supports (HB01508) and 2 end covers (HB01573). This will be the first part of any system bill of material utilizing rectangular busbar between 12 x 5 - 30 x 10.
